Avantages
For the most part, REALLY smart people. A CEO who "gets" strategy and is open to other people's opinions. A strong focus on customers added to the strengths resulting from a data-driven culture (at least through 2008) made it a place where you could be proud of the work you did.
Inconvénients
In 2008, Intuit acquired a small unprofitable company whose CEO happened to be the golden child of Intuit's Chairman. While this acquisition only affected the Mountain View headquarters (Intuit's Small Business Division), it had a dramatic impact on the culture. The environment rapidly shifted from a focus on rational and data-driven decision making to an environment where self-serving opinions, politics and strong-arming of employees became the norm. This shift is mainly attributable to that small company's CEO being "integrated" into Intuit's ranks despite his open contempt for Intuit's ways. Intuit's culture needed to change. But changing a culture to adapt to a new reality doesn't mean you need to violate the company's core values such as "it's the people", "integrity without compromise" or "think smart, move fast." Unfortunately, these values are now being trampled on a daily basis. Today, a much larger number of employees is looking to leave. Screaming in meetings is apparently no longer frowned upon and employees driven to tears is becoming habitual.
